image create

Anon

Hello, i'm using image create and it works on my server, but when i try to put text and php code before it, it doesn't work.

It only works if that's all thats coded is the imagecreate code.

Can someone help me.

The code below would work

<?
header ("Content-type: image/png");
$im = @ImageCreate (50, 100)
or die ("Cannot Initialize new GD image stream");
$background_color = ImageColorAllocate ($im, 255, 255, 255);
$text_color = ImageColorAllocate ($im, 233, 14, 91);
ImageString ($im, 1, 5, 5, "display text", $text_color);
ImagePng ($im);
ImageDestroy ($im);
?>

but this just shows a bunch of lksjd0208208asd80ads

here is some text...

I even tried to comment out the header code

Thanks for your help,
Mark

You can not output HTML, text, or anything else if your script is also outputting the image that you are creating. Either you are going to output HTML or the image, but not both.

If you goal is to create an image that will show up in the web page that you are outputing, then you have to have one script output the html and then have that reference another page that generates the image:

============================
<?php
// "genhtml.php"

print "\n";
print "<HEAD><TITLE>genhtml.php</TITLE></HEAD>\n";
print "<BODY>\n";

// use an image tag that sources the script that will
// generate the image
print "<IMG SRC='genimage.php'>\n";

print "</BODY>\n";
print "\n";

?>

<?php
// "genimage.php"
// This script will generate and output ONLY your image!

header ("Content-type: image/png");
$im = @ImageCreate (50, 100)
or die ("Cannot Initialize new GD image stream");
$background_color = ImageColorAllocate ($im, 255, 255, 255);
$text_color = ImageColorAllocate ($im, 233, 14, 91);
ImageString ($im, 1, 5, 5, "display text", $text_color);
ImagePng ($im);
ImageDestroy ($im);

?>
